GAS REGULATOR AND EQUALIZER FOR GAS-ENGINES.

SPECIFICATION forming part of Letters Patent No. 420,169, dated January28, 1890. Application iiled August 14, 1889. Serial No. 320,711. (Nomodel.)

.To @ZZ whom t may concern:

Be it known that I, WILLIAM O. ROSSNEY, of Hyde Park, in the county ofNorfolk, State of Massachusetts, have invented a certain new and usefulImprovement in Gas Regulators and Equalizers for Gas-Engines, of whichthe following is a description sufficiently full, clear, and exact toenable any person skilled in the art or science to which said inventionappertains to make and use the same, reference being had to theaccompanying drawings, forming part of this specification, in which-Figure 1 is a central vertical section of my improved regulator, partsbeing shown in elevation; Fig. 2, an enlarged sectional view of theback-pressure valve, and Fig. 3 a sectional elevation illustratingcertain modifications in the formation of the main valve.

Like letters and figures of reference indicate corresponding parts inthe different iigures of the drawings.

In gas-engines wherein the piston is driven by the explosion of ordinaryilluminating or water gas the force thereof causes a backpressure of gasin the main pipes, which frequently extinguishes the lights in otherplaces supplied from said pipes. To overcome this, it has becomecustomary to employ large rubber bags or receivers, into which the gasis forced by the concussion, and which serve in part to equalize thispressure. The action of the gas upon the material of.these bags rapidlycauses them to become brittle or decomposed, rendering them dangerous touse and necessitates their frequent renewal. Moreover, the directpressure of the gas in the main pipes varies to a great extent andrenders the action of the engine uneven.

My invention is designed to overcome these land other objections, and incarrying it out I make use of means which will be readily understood byall conversant with such matters from the following explanation.

In the drawings,A represents the body of the regulator, and Bvthe supplyand O the discharge pipe.V The body is constructed of castiron and iscylindrical in form. A cover h is secured thereto by bolts d. Averticalcylinder D is secured to the bottom g within 'said body, said cylinderbeing open at its top f. A verticallyarranged socket or guide-tube h issecured centrally to the bottom g within the cylinder. A spindle H,provided on its upperend with a knob or weight c', is fitted to slidevertically through the center of the cover b, the lower end of saidspindle working in the guide 7L. An inverted dome 0r bell K is securedcentrally to the spindle by nuts j and incloses the cylinder D, themouth of said dome being immersed in aseal of glycerine, mercury, orsimilar material p, disposed between the cylinder and body walls. Avertically-adjustable cone-shaped disk m is secured to the spindle Hwithin the cylinder.

The supply-pipe B is provided with an ordinary valve q and enters thebody vertically through the bottom g and within the cylinder. The upperend rof the supplyis turned horizontally toward the spindle, andagravityvalve t is hinged to the lower edge of the mouth thereof. Thevalve t is provided with a curved arm fwhich normally rests upon the.disk m. A small pipe w taps the pipe B below the regulator and suppliesthe pilot-light of the engine.

The discharge C has an ordinary valve outside the regulator and entersvertically through the bottom thereof within the cylinder. The upper endy of the discharge is turned horizontally toward the spindle. Within themouth of this horizontalportion a coneshaped piece of piping .e (seeFig. 2) is inserted in the inner end of said pipe, being inclined at 15to form avalve-seat. A swinging valve 16 is hinged at 17 by its upperedge within the pipe y in position to engage the seat 15. Thegravity-valve t is normally open. The gas entering through pipe B causesthe dome K to rise and carry with it the spindle H, to which it issecured. The disk m on said spindle, engaging the valve-arm o, elevatesvsaid arm as the dome rises and closes or partially closes the valve t,thus reducing the supply of gas. Atthe forward stroke of theenginepiston, which creates a vacuum in the piston-cylinder, the gasrushes into the discharge O, causing the swinging valve 16 to assume theposition shown by dotted lines 18 in Fig. 2. As the gas thus supplied tothe en- IOO gine is exploded by the pilot-light in the ordinary mannerand is forced back through pipe C by the recoil, the valve 16 is swungback against its seat 15, (see dotted line 19, Fig. 2,) closing saidpipe and preventing the escape of gas under increased pressure back intothe regulator. It will be seen that by the use of this construction therecoil from the engine can have no effect upon lights supplied from themain pipes.

The variations of pressure in the main pipe being determined, theposition of the dome on the spindle H may be so xed as to regulate thesupply of gas to the engine at any desired pressure by means of the diskm and valve t, in a manner readily understood by all conversant withsuch matters without a more explicit description.

In Fig. 3 a lever 2O is pivoted in the top of a standard 21, secured tothe bottom g, between the tube h and supply B. A cone-valve v23 ispivoted to one end of the lever, and a seat 24 therefor is formed in atube 25, into which the supplyB opens. A counter-balance 26 is disposedon the opposite end of the lever, and a wheel 27 is journaled therein,said wheel resting on the disk m. The spindle II, rising, as described,forces the cone-valve 23 down- Ward into its seat 24 and checks the flowof gas into the regulator.

Having thus explained my invention, what I claim is- 1. The'combinationof a body, a cylinder therein, a spindle passing through the cover ofsaid body, a liquid-sealed dome attached to said spindle and inclosingsaid cylinder, a supply-pipe provided with a valve, a disk on saidspindle for engaging the arm of said valve, an outlet-pipe extendinginto said cylinder and provided with a horizontal inlettube, acone-shaped mouth-piece within said tube, provided with an inclinedvalve-seat at its inner end, and a swinging valve hung Within said tubeadjacent to said valve-seat, substantially as described.

2. In a gas-regulator, the body A, dome K, and spindle H, bearing thedisk m, in combination with the supply B, provided with the valve havingthe arm' o, the discharge-pipe C, provided with the pipe z, having theinclined seat 15, and the swinging valve 16, arranged to operatesubstantially as described.
